The idea is to deposit surface state electrons (SSE) on a thin layer of liquid helium covering the surface of a solid state sample. The density of the SSE adjusts to screen perturbations of the electrostatic potential across the sample. As a result, the helium layer thickness varies due to the variation of the electrostatic pressure, thus providing a map. This map may be read interferometrically by a technique already employed for the investigation of multi-electron dimples on helium. We realized this mapping for a structured metal electrode as a test sample to investigate the resolution of the method.</dcterms:abstract> <dc:format>application/pdf</dc:format> <dcterms:rights rdf:resource=""/> <dcterms:available rdf:datatype="">2011-03-24T17:55:10Z</dcterms:available> <dc:language>eng</dc:language> <dc:date rdf:datatype="">2011-03-24T17:55:10Z</dc:date> <dcterms:title>Mapping of surface potentials by electrons on a helium film</dcterms:title> <dcterms:bibliographicCitation>First publ. in: Journal of Low Temperature Physics 110 (1998), 1-2, pp. 249-254</dcterms:bibliographicCitation> <dc:contributor>Teske, Ekkehard</dc:contributor> <dc:rights>terms-of-use</dc:rights> <dspace:hasBitstream rdf:resource=""/> <dc:contributor>Leiderer, Paul</dc:contributor> </rdf:Description> </rdf:RDF>
